A ball mill is a type of grinder used to grind and blend bulk material into QDs/nanosize using different sized balls. The working principle is simple; impact and attrition size reduction take place as the ball drops from near the top of a rotating hollow cylindrical shell. The nanostructure size can be varied by varying the number and size of ...

The working principle of centrifugal pump: (1) The impeller is rotated by the pump shaft to work on the fluid between the blades. The fluid is subjected to centrifugal action and is thrown to the periphery by the center of the impeller. When the fluid reaches the periphery of the impeller, the flow

Principle of Centrifugation. In a solution, particles whose density is higher than that of the solvent sink (sediment), and particles that are lighter than it floats to the top. The greater the difference in density, the faster they move. If there is no difference in density (isopycnic conditions), the particles stay steady.

Understanding Centrifugal Pump Curves When selecting a centrifugal pump, one should match the performance of the pump to that needed by the system. To do that, an engineer would refer to a pumps composite curve. A typical composite curve includes the pump performance curves, horsepower curves and NPSH required.

The casing of a centrifugal compressor will be approximately similar to the casing of a centrifugal pump. Casing is basically an air tight passage surrounding the impeller and will be designed in such a way that the kinetic energy of working fluid (let us say air) discharged at the outlet of the impeller will be converted in to pressure energy before the fluid leaves the casing …

Introduction of Centrifuge . Benjamin Robins (1707–1751), an English military engineer invented a whirling arm apparatus to determine drag. Later in 1864, Antonin Prandtl proposed the idea of a dairy centrifuge to separate cream from milk and his brother Alexander Prandtl became able to exhibit a working butter fat extraction machine in 1875.
